Long Range Standoff Weapon (LRSO)
Development and procurement requests are documented without converting undisclosed missile quantities into an invented unit cost.
Comparable unit price
Not verified
No comparable standalone unit price was established; package or contract totals are shown separately.
U.S. inventory
Not verified
A current U.S. inventory was not established. Annual procurement, cumulative deliveries and production capacity are not a stockpile count.
U.S. procurement quantity
Not verified
The public MLRSO1 procurement table does not provide a usable production quantity; no quantity is inferred from funding.

MLRSO1 P-40, excludes current-year advance procurement shown separately.
U.S. Air Force ↗Current-year advance procurement request

Long-lead funding for future procurement; not an additional delivered missile quantity.
U.S. Air Force ↗Keep advance procurement and warhead development separate
The budget’s total obligation authority already combines net procurement with current advance procurement. The LRSO missile program and its nuclear warhead are separate acquisition efforts; the figures here do not claim a combined weapon-plus-warhead price.
Operations & sustainment
Annual operations & support
Not verified
A complete, system-specific annual operating and support cost was not established. Procurement, replacement rounds and contract support are different measures.
Cost over time · 6 observations
Each row retains its original scope and dollar basis. Changing quantities, service life and inflation can change the estimate without changing the price of building one unit.
